Haruka Nanami never really understood the reason as to why Saotome had the 'No Date' rule. Sure, she could see how it could become awkward if someone in the industry was to break up and then have to deal with each other at work, but that happens anywhere anyways, doesn't it? When a certain idol, who goes by the name of Emi Aoi, suddenly appears, though, the young composer slowly begins to understand the reasoning.
Not many people knew about Y/N L/N, it seemed that even her classmates were quite oblivious to the shy nerdy girl who tended to sit in the back corner of the classroom. Perhaps that is why it comes as a surprise when the greatest idol of her time reveals herself, years later, as this once shy student.
Sora and her twin brother Subaru decide to pursue a life as an idol duet by enrolling in Saotome Academy - with the hope of getting a national debut. While there, they make friendships with the boys who will one day make up STARISH, as well as the shy composer Nanami. While they work hard to make their dreams come true; only one group can debut, but for Sora, losing is unthinkable - and would result in going back to being a bed-ridden hospital patient.
